KENNEDY SPACE CENTER, FLA. - Seen in the foreground is STS-121 Michael Fossum, who is looking at the integrated cargo carrier, part of the payload for the mission, temporarily stored in the payload changeout room on Launch Pad 39B. He is dressed in a clean room suit, appropriate for the environmentally clean or "white room" condition in which the payload resides before being transferred to the shuttle's payload bay. In front of and below him is the multi-purpose logistics module Leonardo, which is carrying supplies and equipment for the International Space Station. The payload also includes the lightweight multi-purpose experiment support structure carrier. Crew members are at NASA's Kennedy Space Center for Terminal Countdown Demonstration Test activities, which include equipment familiarization and a simulated launch countdown. Mission STS-121 is scheduled for launch on Space Shuttle Discovery on July 1. Photo credit: NASA/Kim Shiflett
